Here at Accalia we understand that every body is different and every menstrual cycle is too. When choosing and testing Accalia products for menstruation we can guide you based on our technical knowledge of the product, however, please keep in mind that your personal preferences, flow rate and volume are big factors as to how these products will work for you during your cycle. We would suggest testing your Accalia products at home before venturing out in your best pair of light coloured pants!
